今天中午我在家正写作业 ，听到有人咚咚的敲门。爷爷把门打开，姐姐冲了进来。原来是姐姐放假从郑州回来了。她一进屋就把她的包扔到沙发上，迅速打开，掏出来一套文具，她走到我面前说：“弟弟，这是我送给你的礼物。”我说：“谢谢姐姐。”我俩都开心的笑了。
I was doing my homework at home this noon and heard someone knocking at the door. Grandpa opened the door and my sister rushed in. It turned out that my sister came back from Zhengzhou on vacation. As soon as she entered the room, she threw her bag on the sofa, opened it quickly and took out a set of stationery. She came up to me and said, "Brother, this is a gift for you." I said, "Thank you, sister." We both laughed happily.
